Gilded Bloodscale Dragons often spend hours investigating every minute detail of caves, making sure their living spaces are arranged exactly how they like. They crave intellectual stimulation and get bored easily. As such, these dragons prefer to lure in their prey using their sharp minds rather than brute strength, often engaging in battles of wits between their two heads to determine how best to proceed. Seen as eccentric by other dragons, they are often shunned by all but their own kind.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Two-headed dragons are unique enough to deserve a separate classification from ordinary dragons. They have two necks, two brains, two mouths, but one stomach and one main body. The two heads usually work together, but there are times when they will fight each other, snapping back and forth. Their unique anatomy prevents them from breeding with single-headed dragons.

Energetic and always looking for confusion, Ideo and Affectus are cynical and provocative but above all, very intelligent. Both heads don't even hide their sadistic personality, and if someone enters their cave by accident the two heads would have fun with their favorite game: "Answer me or I'll devour you". The question is usually about logic or some kind of enigmatic riddle but depending on the subject, the question may change and be about anything, even about math. Each head asks a different question and the loser may be devoured or if he has any "potential" he will be made as a prisoner to serve them and entertain them intellectually. The winner is rewarded with his life and the right to own one their treasures, even if both hate losing... The two brothers act like brats and are very close to each other; Affectus is usually the emotive one and the one who tries to cheat while Ideo tries to be fairer and calmer.
